“…Also, various effects on the dispersion of MWCNTs in organic solvents and in polymer lms by means of pyrene-containing polymeric surface modiers were investigated. 137 Gra surface modiers of poly(ethylene oxide) and polystyrene with pyrene groups were synthesized by radical co-polymerization of the corresponding macromonomers and a pyrene-containing methacrylate monomer. The dispersibility of MWCNTs in THF was improved with increasing pyrene content in the gra polymer and was also improved by a branched architecture of the polymeric noncovalent surface modier.…”

Contemporary methods for dispersion of carbon nanotubes in water and non-aqueous media are discussed. Most attention is paid to ultrasonic and plasma techniques and other physical techniques, as well as to the use of surfactants, functionalizing and debundling agents of distinct nature (elemental substances, metal and organic salts, mineral and organic acids, oxides, inorganic and organic peroxides, organic sulfonates, polymers, dyes, natural products, biomolecules, and coordination compounds). Special studies on CNTs solubilization are examined.

“…Furthermore, copolymers consisting of PS and PEO macromonomers as well as Py2 were utilized for the dispersion of multi-walled carbon nanotubes (MWCNTs) in organic solvents. 107 The role of the p-p interactions was also investigated by the group of Bucknall who focused their attention on poly(9-vinylphenanthrene)s (polyP1) with C 60 fullerenes. 108 The results were compared to the PS and polyN3 as homologous series.…”

This review focuses on side-chain functionalized polymers derived from direct (co)polymerization of fluorescent dyes. This overview about polymerizable dyes includes 1,8-naphthalimides, fluoresceins, rhodamines, coumarins, azo-dyes, oxadiazoles, diverse aromatic dyes as well as selected other dyes that cannot be classified within these groups. The discussed dyes have been functionalized with a polymerizable unit in order to apply straight-forward polymerization procedures. Therefore, the center of attention is set to the optical properties of the polymerizable dyes and the applicable polymerization techniques. Furthermore, the various applications (i.e., in biomedicine and pharmacy, as thermo-responsive materials and energy transfer materials, for dispersion of carbon nanotubes and others) of each polymer are discussed.

Cyclic graft copolymers consisting of poly(p‐methylstyrene) backbone and polystyrene branches with relatively low molecular weight distribution are synthesized with grafting‐from approach by living anionic polymerization of styrene from lithiated cyclic poly(p‐methylstyrene)s as multifunctional anionic macroinitiators for vinyl polymerizations. Precursors of the macroinitiators are prepared by ring‐closing metathesis reaction of α,ω‐divinyl‐terminated telechelic polymers. Subsequently, selective lithiation of tolyl groups in the cyclic polymers is conducted by s‐BuLi in the presence of tetramethylethylenediamine in cyclohexane in order to prepare the macroinitiators. Addition of styrene monomer into the cyclic macroinitiators provides shift in SEC to higher molecular weight due to graft polymerization from the macroinitiators to form cyclic graft copolymers. The unique polymer architecture of the obtained cyclic graft copolymers is confirmed by unimolecular observation by using atomic force microscopy.
